Apple Updates Logic Pro and MainStage, Adds 64-Bit Compatibility

The Loop notes that Apple has released Logic Pro 9.1 and MainStage 2.1, bringing several bug fixes to the company's professional audio applications, as well as 64-bit compatibility for users running Mac OS X 10.6.2 or later.

Adding 64-bit support to Logic 9.1 and MainStage 2.1 effectively removes the memory limit imposed on 32-bit applications running under Mac OS X. When running the apps in 64-bit mode, users can take advantage of any memory left after allocating the system, plug-ins and other apps.

As addressed in an Apple FAQ support document, users of 32-bit plug-ins will be able to use Logic Pro and MainStage in 64-bit mode, with Apple's new 32-bit Audio Unit Bridge serving to provide compatibility with those plug-ins.

The report also notes that there are several features in Logic Pro and MainStage that are not yet functional in 64-bit mode, so users should make note of those limitations before deciding which mode to use. Full details of the changes in Logic Pro 9.1 and MainStage 2.1 are available in release notes posted on Apple's site.

Apple released its updated Logic Studio suite in July and had issued a couple of minor updates before today's major point release.

omg srsly? Bug Fixes? A .1 update? 64-bit?? :D

I was thinking of moving most of my production to Ableton cuz of all the little annoying bugs and memory errors. This might keep me on Logic.

I know your pain. I'm used to Logic 8's bugs but I'm slowly getting used to Logic 9's bugs. Will give the update a try, looks like they fixed quite a lot of stuff.

let's hope this fixes the memory bug from hell.....

It has been slowing me down massively.

updating now...

64 bit? Hint: Wrap your arms tightly around your old audio apps, no matter what these people say about clarity. Remember that rush and return to old 60s and 70s gear? The value of old amplifiers and equalizers and mixing boards sky-rocketed. Vintage 16 bit recording is going to be huge in a few years after people complain about the weird lack of character and hyper-clarity of 64 bit recording.

For convenience we'll record in 16 bit and then edit in 64 bit.

Think of one word, people: TONE.

64-bit is NOT relating to the sound quality. This update is upgrading the program's architecture to accommodate more RAM -- right now 32-bit caps off at 4GB of RAM. Lots of sample libraries are 2GB+, and Logic users have been running into memory issues.

Right now all (most?) audio programs have internal 32-bit editing, regardless if you choose to record in 16-bit or 24-bit. I don't believe there are any 64-bit capable audio interfaces out right now.

Is this NOT about 64-bit samples. This is about the width of pointers on the software. 32 bit pointers allow you to "only" address 4GB or memory per process.

Going to 64 bits means now you can use four billion gigabytes of RAM (Yes, I'm not kidding) should you happen to have that much installed in your Mac.

Nothing to do with Sample size.

How much data can you fit into a 64 bit space? About 45,000 years of streaming video.
